#4 Doyle Erickson from Bagley MN in his Midwest Modified racing hard at the The Legendary Bullring River Cities Speedway. Rumor has it Doyal changed his number from 99 to 4 this year to honor his nephew Riley Erickson who passed away from cancer in 2006 when he was 11 years old. He would've graduated this year. Riley raced number 4 in motocross.
